You'll find that all Solicitors are the same - they all insist that their client's claim is more important.(posted 7786 days ago)Why not ask them how they think you can pay £130 if you've only £109 a month left and how do they expect you to get the rest? See what they say - if nothing else its causing them more work in having to reply to you.
I assume that the 8k is a fully justified claim against you, if not, then stop paying Eversheds and get all the paperwork about your case. There is information on this website about what you can do.
